Unknown Error

There are several causes for this error. Some common causes are:

There are user accounts on your cluster that have a user ID less
than the value specified for the min.user.id
property in the container-executor.cfg file.
The default value is 1000 which is appropriate on Ubuntu
systems, but may not be valid for your operating system. For
information about setting min.user.id in the
container-executor.cfg
file, see this
step.

This error is often caused by previous errors; look earlier in
the log file for possible causes.
